Adjustable Trolley Grip Structure for Ergonomic Angle and Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trolleys lack the ability for users to adjust the handle or grip to desired angles and heights based on their height and using requirements, causing inconvenience.
Innovation Solution
A handle structure with two grips that can be adjusted to various angles and heights through a design comprising first and second fixing portions and a body with extending and connection portions, allowing users to grip at desired positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle structure uses a fixed single-position design, then the structure is simple, but the user cannot adjust to desired angles and heights causing using inconvenience
Solution Approach 1:
The handle structure is divided into multiple segments: a first fixing portion, a second fixing portion, and a body with multiple extending portions. Each segment can be independently positioned and fixed, allowing the handle to be segmented into different configurable sections that can be adjusted to various angles and heights while maintaining structural integrity
Solution Approach 2:
The handle structure transitions from a fixed design to a dynamically adjustable one. The body includes multiple extending portions that can be positioned at different angles and heights, and fixed to the fixing portions at desired locations. This dynamic configurability allows users to adjust the handle according to their height and usage requirements, resolving the contradiction between simplicity and ease of operation
2Adaptability or versatility
If the handle structure is designed with multiple adjusting positions and angles, then user comfort is improved, but the structural complexity increases
Solution Approach 1:
The handle structure is designed with universal adaptability through multiple extending portions that can serve different functions. The body includes first, second, and third extending portions that can be fixed at various positions to accommodate different user heights and usage scenarios. This multi-functional design allows a single handle structure to serve multiple purposes and user requirements without requiring multiple separate handles
Solution Approach 2:
The handle structure employs a nested configuration where the body with its multiple extending portions is integrated within the overall handle assembly. The extending portions can be nested or folded when not in use, and deployed when adjustment is needed. This nesting approach allows the complex multi-position structure to be compact when not fully extended, reducing the apparent complexity while maintaining full adjustability functionality

AI summary
A handle structure of a trolley contains: two grips symmetrically mounted on the trolley, and a respective one grip includes: a first fixing portion, a second fixing portion, and a body. The first fixing portion is configured to be connected with the trolley. The second fixing portion is configured to be connected with the trolley and located below the first fixing portion. The first fixing portion and the second fixing portion are on an axial line. The body is defined between the first fixing portion and the second fixing portion, a first end of the body is connected with an outer side of the first fixing portion, and a second end of the body is connected with a rear side of the second fixing portion; the body includes a first extending portion, a first connection portion, a second extending portion, a second connection portion, and a third extending portion.
